Lokring has received NSF 61: Drinking Water System Components – Health Effects and NSF 372: Drinking Water System Components – Lead Content certification for its PW line of stainless steel fittings.

Lokring Technology LLC, a leading provider of advanced pipe and tubing connector products for global fluid and gas transfer markets, announced today it has attained NSF 61 and NSF 372 certification for its line of stainless steel “PW” fittings and the facilities that manufacture them. Already ASME B31 code qualified for use on 316 SS piping, the addition of NSF certification means these fittings can now be safely used in potable water applications in full compliance to the U.S. Safe Drinking Water Act.

“Lokring has always remained dedicated to the relentless pursuit of perfection in understanding and satisfying the industry’s fluid and gas connection requirements,” said Bill Lennon, President, Lokring Technology LLC. “Being able to offer a weldless solution that meets our customer’s needs for safe, healthy, and clean drinking water is an accomplishment we are extremely proud of.”

NSF 61 certification applies to the Lokring global manufacturing headquarters facility in Willoughby, OH. Certified products include the following configurations in 1/4” to 3” NPS and 1/4” to 2-1/2” tube sizes:

SS40-ADPT-FPT-PW

SS40-ADPT-MPT-PW

SS40-CAP-PW

SS40-CPL-PW

SS40-EL45-PW

SS40-EL90LR-PW

SS40-EL90SR-PW

SS40-FLNG-PW

SS40-RED-PW

SS40-RTEE-PW

SS40-TEE-PW

Certification to NSF/ANSI Standard 61 (C0355268-061) and Standard 372 (C0355268-372) confirm that Lokring potable water fittings meet the requirements of the 2014 Amendment of the U.S. Federal Safe Drinking Water Act. This recognition marks an important milestone for the company, adding potable water to the growing list of applications where a code-qualified hot-work-free solution is available through Lokring.

Lokring couplings and fittings are ideally suited for fast-track or cost-effective fabrication of small bore piping and tubing systems, as well as field modification and repair of existing piping and tubing systems. Lokring is a highly efficient alternative to welding and is consistent with good engineering practice in the design and construction of piping and tubing systems.

The Fitting Applications Guide provides consumers with an overview of the Lokring fitting, providing details on the technology behind the fitting, how it can and cannot be used, how to take corrosion into account, and what ASME codes the fittings meet. In addition, a pressure-temperature reference guide is included, along with what fitting to use for most standard pipe grades and types.

Lokring couplings and fittings are ideally suited for fast-track or cost-effective fabrication of small bore piping and tubing systems, as well as field modification and repair of existing piping and tubing systems. Lokring is a highly efficient alternative to field welding or flanging and is consistent with good engineering practice in the design and construction of piping and tubing systems.

This comprehensive guideline is an essential tool for those designing pressure piping projects that use Lokring ESP fittings. It provides information on materials of construction, pressure-temperature ratings, thermal expansion design and weight distribution and support. In addition, details on load designs, pipe supports, special fittings, pull-out and torsion and installation is included.

Many Small-Medium sized Enterprises (SMEs) thrive because their partnership with large global companies in America allows them to reach new customers in international markets, boost their revenue, and generate new ideas and best practices that enhance their competitiveness. A concrete example of the two-way benefits of such partnerships is ExxonMobil’s commitment to finding technical solutions to its global business challenges through mutually beneficial partnerships with key suppliers like Lokring Technology, which employs just under 100 workers at its Cleveland, OH headquarters.

ExxonMobil identified a new alternative to hot work welding in 2007 when they came across a pipe fitting technology created by Lokring during their MEV (Maintenance Efficiency Venture) initiative. At the time Lokring was already a supplier to ExxonMobil. This relationship deepened with the MEV decision to support the use of Lokring’s pipe-fitting technology. Lokring fittings require no heat, is quick to install, and can be used by properly trained technicians without any welding experience.

Lokring Technology LLC is pleased to announce that the Louisiana Department of Environmental Quality (LDEQ) has recognized our patented Elastic Strain Preload (ESP®) technology and pipe and tube fittings as “weld equivalent connectors.” This is a significant achievement and recognition of Lokring Technology as these joints (connectors) are at minimum equivalent to a welded joint, and therefore “exempt from any and all monitoring requirements for purposes of fugitive emissions as specified in LAC 33: Part III. sections 21/21 and 21/22” (attached). Please reference pg.160-169 of The Environmental Regulatory Code (May 2012 revision), LAC33: Part III. Sections 21/21 and 21/22.
